- *	IP firewalling code. This is taken from 4.4BSD. Please note the
- *	copyright message below. As per the GPL it must be maintained
- *	and the licenses thus do not conflict. While this port is subject
- *	to the GPL I also place my modifications under the original
- *	license in recognition of the original copyright.
- *
- *	Ported from BSD to Linux,
- *		Alan Cox 22/Nov/1994.
- *	Merged and included the FreeBSD-Current changes at Ugen's request
- *	(but hey it's a lot cleaner now). Ugen would prefer in some ways
- *	we waited for his final product but since Linux 1.2.0 is about to
- *	appear it's not practical - Read: It works, it's not clean but please
- *	don't consider it to be his standard of finished work.
- *		Alan.
- *
- * Fixes:
- *	Pauline Middelink	:	Added masquerading.
- *	Jos Vos			:	Separate input  and output firewall
- *					chains, new "insert" and "append"
- *					commands to replace "add" commands,
- *					add ICMP header to struct ip_fwpkt.
- *	Jos Vos			:	Add support for matching device names.
- *	Willy Konynenberg	:	Add transparent proxying support.
- *	Jos Vos			:	Add options for input/output accounting.
- *
- *	All the real work was done by .....
